How We Built It
07- System Architecture
- Microservices architecture with API Gateway pattern, event-driven design using Kafka for asynchronous processing, and containerized deployment on Kubernetes for high availability and auto-scaling.
- Database Architecture
- PostgreSQL primary database with read replicas for scaling. Redis for caching and session management. MongoDB for logging and analytics. Data partitioning by merchant ID for horizontal scaling.
- Infrastructure
- AWS multi-region deployment (US-East, EU-West, AP-Southeast) with CloudFront CDN, RDS PostgreSQL with read replicas, ElastiCache Redis clusters, S3 for file storage, and CloudWatch for monitoring.
- Scalability
- Horizontal scaling with Kubernetes auto-scaling based on CPU/memory metrics. Database sharding for multi-region deployment. CDN for global content delivery. Load balancing across multiple availability zones.
